Voice use of nurses working in the intensive care unit during the COVID-19 pandemic.

Publication date: Jan 16, 2024

This study aimed to investigate the voice use of nurses working in intensive care units (ICUs) and their perception of acoustic environments. The research was conducted in four different hospitals in China during the COVID-19 pandemic. A total of 60 ICU nurses were recruited for their voice use monitoring and 100 nurses participated in the survey. Firstly, voice-related parameters such as voice level (SPL, dB), fundamental frequency (F0, Hz), and voicing time percentage (Dt, %) were measured using a vocal monitor. To collect data, a non-invasive accelerometer was attached to the participants’ necks during their working hours. Secondly, the perception of the ICU acoustic environment was assessed using semantic differential. The results showed that nurses spoke approximately 0. 9-4 dB louder to patients and colleagues in ICUs compared to quiet rooms, and their fundamental frequency (F0) significantly increased during work. The voice levels of nurses were influenced by background noise levels, with a significant correlation coefficient of 0. 44 (p
